Rep. Mike Pompeo, R-Kan., accused the NPR ombudsman of whitewashing the media outlet’s decision to take money from proponents of the Iran deal and interview those experts without disclosing it to listeners.

“It fails to answer any of the core questions regarding NPR’s role in acting as an agent of the White House during the debate regarding President Obama’s deal with the Ayatollah Khamenei,” Pompeo said in a statement late Friday.
